Claims29
A turbine blade comprising:
- an airfoil integrally formed at a root with a platform and mounting dovetail;
- said airfoil having a plurality of flow channels extending in span from said dovetail to an outer tip thereof, and adjacent channels being separated by a corresponding primary partition having an inner saddle;
- and
- a bipedal damper having a pair of legs extending in span into corresponding ones of said channels and integrally joined together at a seat bridging said saddle.

A turbine blade comprising:
- a hollow airfoil including opposite pressure and suction sides extending in span between a root and tip, and extending in chord between opposite leading and trailing edges;
- a platform and an integral dovetail affixed to said airfoil root;
- said airfoil further including a plurality of flow channels separated by corresponding partitions and extending in span between said root and tip;
- said partitions including a primary partition having an inner saddle at an inner end thereof;
- said flow channels including a common inlet extending through said dovetail and platform to said airfoil;
- and
